Feeling guilty

Mo • Mama ×3 ❤

So I breastfed for a month and then decided to exclusively pump. I have been doing this for 3.5 months. So technically breastfeeding for 4.5 months. Lately, my supply has been sooo low. I asked for some advice on an earlier post and I have tried everything. I tried power pumping, eating certain things, drinking lots of water, etc. Due to my constant pumping, I don't sleep until 2am. I wake up at 4 to feed and I am up again around 8. I haven't been able to rest very much and it is affecting me as a mother. I don't feel happy and I am always tired. A part of me wants to quit but I feel so guilty. I don't know what to do.. I feel like I am being selfish.
